This is based on the Albert Einstein’s Theory of Special Relatively, published in 1905, in which an object moving at the speed of light would experience time slowing down.

Oxford-born genius Hawking, who died today aged 76, echoed the movie franchise Back to the Future in predicting that a person moving fast would see their clock slowing down while time would stay the same for people who were moving normally.

Prof Stephen Hawking: “Time travel was once considered scientific heresy. I used to avoid talking about it for fear of being labelled a crank. But these days I’m not so cautious. In fact, I am obsessed by time.”

Speaking at the Web Summit in Lisbon last year, Hawking said: “We cannot know if we will be infinitely helped by AI or ignored by it and sidelined, or conceivably destroyed by it.

“AI could be the worst invention of the history of our civilisation, that brings dangers like powerful autonomous weapons or new ways for the few to oppress the many.”

“AI could develop a will of its own, a will that is in conflict with ours and which could destroy us. In short, the rise of powerful AI will be either the best, or the worst thing ever to happen to humanity.”
